Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed November 23, 1918. Serial No. 263,868.

To all whom it may concern:

Be it known that I, ARTHUR Gr. TOLMAN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Means of Applying Sheathing to Corrugated Roofing; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention is directed to the provision of an improved means of repairing corrugated roofing and has for its primary object the provision of a means of applying sheathing material in a most ready manner over large areas of roofing to effectively seal openings which may be formed in the roofing by rust or other causes and to procure a permanent surface which will be proof against damage by the elements.

A further object resides in the provision of a means of repair which utilizes the damaged corrugated roofing as a body or base on which to apply sheathing material.

In describing my improved means, reference is had to the accompanying drawings which illustrate the application and steps of the means, and in which Figure 1 is the upper portion of a building having a roof of corrugated metal and showing the characteristic decay to which said roof is subject by continued action of the elements.

Fig. 2 is a sectional view through a portion of the roofing showing the first step of my repair means.

Fig. 3 is a similar view showing the second step of my means, and

Fig. 4 is a similar view showing the final step of my means.

Referring now more particularly to the accompanymg drawings, 5 designates a body of corrugated roofing which islaid over the usual beams 6 and in which leak permitting openings a have been formed in the usual processes of deterioration under influence of the elements. In carrying out my improved method, the first step is to apply a coating 7 of tacky plastic material to the surface of the roofing as a binder, this material also plugging the openings therein.

The second step is to apply a sheet 8 of tar paper or the like to the roof, and the third step is to press the sheet 8 firmly upon the corrugated roofing in conformity with the undulations of its surface to procure firm adhesion of the sheet 8 to the roofing over the entire repaired area.

' This pressing of the repair sheet is lprogressively performed by an instrument aving alternate ridges and depressions on its pressure face mating with the ridges and depressions of the roofing surface, and the engagement of the ridges of the instrument in the depressions of the roofing surface is such that one ridge is operative to hold the repair sheet in a roofing depression while the next ridge of the instrument acts to draw and depress the repair sheet into the succeeding depression, thus preventing the sheet portion within the first named depression from being disengaged by the drawing action of the succeeding depression. This instrument may comprise a fluted roller 9 as shown in Fig. 4, the undulations of the peripheral surface of the roller corresponding to the undulations of the roofing body 5 to press the sheet 8 into the depressions of said body surface, the roller being of such diameter that adjacent ridge portions of its peripheral surface simultaneously seat in the roofing depressions to prevent drawing of the repair sheet, as set forth. The tacky binder material may constitute tar or any commercial compound possessing the required qualities of adhesion and permanence, and similarly the repair sheathing 8 may be of any material possessing sulficient flexibility and permanence.

An exceedingly simple means of repair has thus been provided which effects a complete seal for the damaged roofing surface, and which may be economically carried out, the otherwise useless corrugated roofing body being utilized as a base for the sheathing.

While I have shown my improved means of repair as applied to corrugated iron roofing, it will be appreciated that it may also be applied to other types of corrugated roofing such as concrete roofing, which is liable to leakage by cracks formed therein, and it is further understood that my improved means of sheathing may be utilized on such roofing as a precautionary meaure against leakage.

What is claimed is:

That improved method of applying sheathing to corrugated roofing which consists in applying a coat of plastic adhesive material to the roofing and then applying a flexible cover sheet to the roofing, and in finally pressing the cover sheet against the roofing by a pressure member having undulations conformin to the undulations of the surface of the roo ng said undulations of the pressure member being successively engaged in sure undulation in forcing the cover sheet the channels formed by the undulations of into a succeeding roofing channel.

the roofing surface, each' undulation of the Intestimonythat I claim the foregoing I 10 pressure member When engaged in the chanhave hereunto set my hand at Milwaukee, in 5 nel of the roofing surface serving to retain the county of Milwaukeeand State of Wisthe cover sheet in place against the tension consin.
